Patent No. 283,560, dated August 21, 1883,

Application filed April 6, (No modclrl To all whom it 11i/ty concern:

Be it known that I, LUDWIG BLornu, a citizenof the United States, residing` at Chicago, in the county of Cool: and State-of Illinois, have invented certain neuv andusei'ul Improvements in Molds for Forming Ornamental Moldf. ings, of which the following is a specification, to Wit:

This invention relates to molds ior forming ornamental moldings; and it consists in the process of constructing the molds, substantially as will be hereinafter more i'ully vset forth. Y

In order to enable others skilled 'in the art to which my invention app e'rtains to m alte and use the same, I will nouT proceed to describe its construction and operation, referring tothe annexed drawings, in Which- Figure 1 is a central longitudinal section of one oi' my molds, and Fig. a plan viewo'the same.

Asnow made, it is usual to construct molds of wood about fourteen inches in length, and in this space the design usually repeats itself several times'. The objection to this method is the time necessary to accuately carve those repetitions of the design, the cost of employing skilled Workmen for the construction of the whole mold, and the care and time neces 'sary in forming or. carving the molds in negative form in order to show a positive when molded. This I remedy in the following 1nanner, viz: Only so much of the design is carved suitable material as forms in the mold-as, for instance, the part inclosed by the dottedlines a d in the drawings. This is much more rapidly and accurately done because carved in relief, as it will appear on the iinished molding. This section is then pressed in Wax or other suitable plastic material, and the impressions are repeated inorder to repeat the design for any length of mold required. The form so made is placed in an electric bath, and its face covered byadeposit of any suitable metal such as copper-which `is evenly and thinly deposited over the whole face ofthe i'orm, and conforms exactly to the de\ signimpressed upon it. Vhen this deposit has formed a sheet, c, of sufficient thickness, it is removed vfrom the bath, and the plastic material in which the form was impressed is removed by heat or other means, and a backing of lead or similar soft metal, b, run in, which forms with the copper face a solid-metal mold, by which'the ornament is formed for use upon the moldings, which will be much more accurate than Where the reproductions of the design are made by carving, is much easier and quicker made, and i'orms a more lasting mold, While leaving the original carving unhurt for future use should afnew mold be desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. "he process herein described for making carving one complete section of the design; second, in pressing this section in plastic materia-l I'vith any desired number of repetitions; third, in forming a metal deposit upon the face of such plastic mold in an electric bath.Y and, finally, in separating the metallic mold thus formed from the plastic material, and providing it with a soft-metal backing, substantially as and for theI purpose herein set forth.

2. A mold for forming ornamental 1nold ings, consisting of a thin sheet of copper or 4equivalent metal, in which the desired ornamental congurations are for'med, in combina tion with a soitmetal backing or base, substantially as shown and described.
